Many people do not know that catalytic combustion equipment needs speed regulation, and do not know what speed regulation is. Today, let's look at the knowledge of speed regulation of catalytic combustion equipment.
There are two purposes for regulating the speed of catalytic combustion equipment. One is to save energy and avoid excessive electricity consumption in the purification system. Second, in order to control the air volume, to avoid the dust removal system suction tuyere suction of useful materials. Today, follow the small series to see how to choose the speed regulation of catalytic combustion equipment.
(1) When the flow varies from 90% to 100%, the energy saving effect of various speed regulating modes is similar to that of the population throttling mode, so there is no need for speed regulating operation.
(2) when the flow rate changes in 80%-100%, the cascade or frequency conversion efficient speed regulation mode should be adopted, rather than the pressure regulation, resistance adjustment, electromagnetic slip clutch and other low-efficiency speed regulation to change the slip rate.
(3) when the flow in the 50%-100% change, a variety of speed control methods are applicable. When the pole-changing speed regulation, the flow can only be stepped change (75%/100%; 67% / 100%).
(4) when the flow is less than 50% change, the frequency conversion speed regulation, cascade speed regulation is appropriate.
(5) matters needing attention when selecting the speed regulating device
(1) the initial investment and operation costs of the speed regulating device.
(2) operation reliability and maintenance requirements of the speed regulating device,
(3) the efficiency and power factor of the speed regulating device, the effect of electricity saving.
(4) the operation law of the driven equipment, such as the variation range of the fan flow and the running time of different flows.
⑤ Capacity size of the driven device.
(6) on-site technical force and environmental conditions, etc.
